Arrange the following polymers in decreasing order of their intermolecular forces:Bakelite, Polythene, Buna-S, Nylon-6,6Arrange the following polymers in decreasing order of their intermolecular forces:Bakelite, Polythene, Buna-S, Nylon-6,6​

Answer»

Answer:

Hence the decreasing order of intermolecular forces is-

BAKELITE > Nylon-6,6> Polythene > Buna-S

Explanation:

As we know that elastomers (Buna-S) have weak intermolecular forces, FIBRES (Nylon-6,6) have dipole-dipole interaction, thermoplastics (Polythene) have intermolecular forces INTERMEDIATE between elastomers and fibres and thermosetting POLYMERS (Bakelite) undergoes permanent change on heating.
